A numerical investigation is performed using Solidworks^® 2018 (flow-simulation) with results in good agreement with experimental data of the lift coefficient of a Joukowsky profile calculated with the same conditions. The Solidworks is used to study the dynamics for air passing around an aerodynamic profile NACA2415, equipped with rotating cylinder(s). First, the numerical simulation determined the leading-edge of profile, which was the optimum position of the rotating cylinder with an increase of 3 % of CL and diminished to 17 % of CD compared to the basic profile. The second part of the simulation is reserved for the profile equipped with two rotating cylinders, the first cylinder at the leading-edge and the second at 15 % of the chord. This configuration gives the best results with an increase of 74.15 % of CL and diminishes to 12.98 % of CD. Another simulation is launched to consider the influence of diameter variation (Ø) of the rotating cylinder on the CL and CD. This simulation shows that both parameters mark a proportional increase with augmentation of the rotating cylinder diameter until Ø 26 mm, as we note a diminishing of CL when CD increases. As a result, Solidworks^® regroups all its modules on the same interface (fluid, structure, and others); this code is verified to be available and is used in aeronautical engineering.
